Method and apparatus for decomposition treating article having cured thermosetting resin

摘要

There is disclosed a method of decomposition treating a waste article comprising cured thermosetting resin comprising the steps of: (a) bringing the waste article comprising cured thermosetting resin into contact with a decomposing fluid containing a solvent, capable of decomposing the resin, in a decomposition bath and (b) heating the fluid at a temperature not lower than 250 DEG C and lower than the critical temperature of the solvent. Thereby, a waste article containing cured thermosetting resin is easily decomposed and waste resins and other components therein are recycled and reused as resources.
